There are many people who had less income than the filing "requirement" who choose to file in order to seek refunds of the amounts withheld from their paychecks. Even if your grandchild earned less than the 2023 filing threshold of $13,850 for 2023 or $14,600 for 2024, if she has amounts in box 2 or box 17 of her W-2 she can file a return to seek refunds for federal or state tax withheld. TurboTax does not prevent anyone from preparing a return if they have less than the filing requirement.
Information flows from the federal return to the state return, so in order to use TurboTax to prepare a state return, you must first prepare a federal return.
